Bimolecular Fluorescence Complementation assay reveals the Hoxa1-mediated interactions in culture cells. MCF10A cells were transfected with VN173-hORF and VC155-Hoxa1 fusion proteins. Upon interaction between the partner proteins, the VN173 and VC155 moieties of the Venus fluorescent protein brought together provide a fluorescent signal. The interactions between Hoxa1 and its interactors can be classified according to their intracellular pattern: (A) nuclear, (B) cytoplasmic or associated to vesicles, (C) nuclear and cytoplasmic and/or vesicular.
